Ultra violet light sterilization is a proven technology that has been with us for some time. Back in 1903 Niels Finsen was awarded the Nobel Prize for Medicine for his work in using UV to fight tuberculosis and these days it's a common sight in hospitals, food production facilities and science labs, as well as being used for water purification and disinfecting swimming pools. The technology is also increasingly making its way into domestic households with examples like ENPUTECH's UV sterilization wand and this innovation from Oreck - the world’s only UV equipped upright vacuum cleaner.
